Create an automobile class that will be used by a dealership as a vehicle inventory program. The following attributes should be present in your automobile class: private string make private string model private string color private int year private int mileage Your program should have appropriate methods such as: default constructor parameterized constructor add a new vehicle method list vehicle information (return string array) remove a vehicle method update vehicle attributes method. All methods should include try..catch constructs. Except as noted all methods should return a success or failure message (failure message defined in "catch"). Create an additional class to call your automobile class (e.g., Main or AutomobileInventory). Include a try..catch construct and print it to the console. Call automobile class with parameterized constructor (e.g., "make, model, color, year, mileage"). Then call the method to list the values. Loop through the array and print to the screen.…
Java - Constructors Create a class named Book that has the following attributes: Publisher - String Year Published - Integer Price - Double Title - String Create a constructor for the class Book that has the parameters from the attributes of the class. After, create a method for the class that displays all attributes. Ask the user for inputs for the attributes and use the constructor to create the object. Lastly, print the values of the attributes. Inputs 1. Publisher 2. Year Published 3. Price 4. Book Title XYZ Publishing 2020 1000.00 How to Win?

Assignment:The BankAccount class models an account of a customer. A BankAccount has the followinginstance variables: A unique account id sequentially assigned when the Bank Account is created. A balance which represents the amount of money in the account A date created which is the date on which the account is created.The following methods are defined in the BankAccount class: Withdraw – subtract money from the balance Deposit – add money to the balance Inquiry on:o Balanceo Account ido Date created
Hints: • For each class, it is required to implement constructors, setters, getters, toString() method, and any other necessary method • If the user tries to do an operation that could violate the state of objects, the operation should be ignored and the application should display an error message (e.g. adding a passenger to the same trip twice, etc.) Checking equality of any 2 objects should be done via the equals() method • • Testing: After implementing the required classes, design and implement a testing class to test them as follows: There is a class that will do the main job of as follows: o It has one collection to store the whole data (all trips) o It has static methods, one for each operation happens frequently o For each adding or removing operation, a message should be displayed to the user to explain the status of the operation (i.e. if it was successful or not) • Create at least 7 trips in at least 3 different dates and add them to the collection that stores the whole data…
Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Also, write a program that creates three instances of the class. One instance should hold your information, and the other two should hold your friends’ or family members’ information.
Rectangle Object Monitoring Create a Rectangle class that can compute the total area of all the created rectangle objects using static fields (variables). Remember that a Rectangle has two attributes: Length and Width. Implement the class by creating a computer program that will ask the user about three rectangle dimensions. The program should be able to display the total area of the three rectangle objects. For this exercise, you are required to apply all OOP concepts that you learned in class. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Enter Length R3: 3 Enter Width R3: 3 The total area of the rectangles is 14.00 Note: All characters in boldface are user inputs.
Task Performance Amount Due Objective: At the end of the activity, the students should be able to: • Apply method overloading in a program. Procedure: 1. Develop a simple program for an individual savings account. Create two (2) classes named AmountDue (no class modifier) and RunAmountDue (public). 2. For the AmountDue class, create three (3) overloaded methods named computeAmountDue based on the following conditions: With a single parameter: It represents the price of one (1) item ordered. Add 12% tax and return the total due. • With two (2) parameters: These represent the price of an item and the quantity ordered. Multiply the two (2) values, add 12% tax, and return the total due. With three (3) parameters: These represent the price of an item, the quantity ordered, and the discount amount. Multiply the quantity and price, deduct the discount amount, add 12% tax, and return the total due. 3. For the RunAmountDue class, import the Scanner class to be able to use the nextDouble()…
Temp Class - Create Temp class whos job is to hold a temp in degrees F and gives methods to get the temp in F, Celsius, and Kelvin. The class should follow the instance variable (field): ftemp (double type that holds F temp)Follow these methods with the class.. Constructor --Will accept Fahrenheit temperature as a double to store it in the ftemp field.  setFahrenheit - The setFahrenheit method accepts a Ftemperature as a doubleto stores it in the ftemp field.  getFahrenheit - Returns the value of the ftemp field, as a Fahrenheit temperature (no conversion required).  getCelsius - Returns the value of the ftemp field converted to Celsius. [C e l s i u s = ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 )]  getKelvin - Returns the value of the ftemp field converted to Kelvin. [K e l v i n = ( ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 ) ) + 273] Exemplify the temp class by writing a (test) program that is separate and promotes users for an F Fahrenheit temp. The program must create an…
1- Write a Java class that models a Vehicle. There are three types of vehicles (Sedan, SUV, Truck). Every vehicle object should also contain an instance variable that can be used to store the time at which the vehicle has entered the car parking building (Hint: use the java.util.Date class to represent the time). In addition to the constructors, you should provide the following methods: public double getDuration(Date exitTime) this method will return the duration (in minutes) from the time the vehicle entered the parking until the given exitTime. public String getType() this method will return either Sedan or SUV or Truck based on the vehicle type. public void setType(String type) this method will set the type of the vehicle to either Sedan or SUV or Truck. public void setEntryTime(Date entryTime) this method will set the time at which the vehicle has entered the parking.

D: A 21. The method finalize automatically executes when the class object goes out ofI Scope. 22. A mutator method ofa class changes the values of the data members of the class. 23. In Java, the reference this is used to refer to only the methods. not the instance variables of a class.
